Title: Ball grid array
Inventor: TAKAMICHI HIROSHI
IPC: H01L23/12
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To easily mount a removably radiation fin, by forming bends of a metal sheet to form a semiconductor element-housing cavity and forming notches for mounting chip capacitors at the periphery of the bends. SOLUTION: A ball grid array 10 has a cavity 14 formed by formed bends 13 to house a semiconductor element 16.

Title: Fining method for crystal grain of castings
Inventor: YAMAGUCHI MASARU
IPC: B22D27/20
Filed: 1979-02-06
Abstract: PURPOSE: To fine crystal grains and prevent casting cracking by solidifying molten metal through the utilization of an electromagnetic rabbling machine.  
     CONSTITUTION: At the time of casting C-Cr-Al base cast steel, current supply to an electromagnetic rabbling coil 3 is continued until solidification completes at the same instant when molten metal 2 is poured into a mold 1. At this time, the rabbling intensity of the molten metal 2 is determined by magnetic flux density but even at the same magnetic flux density, the rabbling intensity varies with the shape, thickness, etc. of the casting. Because of this, the rabbling intensity corresponding to the magnetic flux density is defined by the velocity of flow of the molten metal 2, whereby the molten metal is solidified within the magnetic field.

Filed: 1998-01-06
Abstract: PROBLEM TO BE SOLVED: To easily produce a spiral wire in a large amt. and to make the pitch, size, etc. of spirals easily changeable by forming a working hole of a die eccentrically with respect to the wire. SOLUTION: The wire 1 drawn out of a wire supply drum 10 is inserted through the working hole 3 existing at the position eccentric from the center 20 of rotation and is mounted at a take-up drum 19. A drive motor 15 and the take-up drum 19 are then rotated. Since the wire 1 rotates around the center 20 of rotation together with the working hole 3 of the die 2, the wire 1 is bent and is spirally formed in the outlet part of the working hole 3. The spiral wire 1a emerging from the die 2 is taken up on the take-up drum 19. If the eccentricity quantity of the working hole 3 is large and the take-up speed is slow, the wire 1a strongly formed with the spirals is obtd. If the eccentricity quantity is small and the take-up speed is fast, the wire 1a weakly formed with the spirals is obtd.  Namely the arbitrary determination of the spiral state is made possible by regulating the eccentricity quantity and the take-up speed.
